The National Weather Service in GRAND JUNCTION has expanded the

* Flash Flood Watch to include portions of northwest Colorado
  and northeast Utah, including the following areas, in
  northwest Colorado, Central Yampa River Basin, Elkhead and
  Park Mountains, Lower Yampa River Basin, and Upper Yampa River
  Basin. In northeast Utah, Eastern Uinta Basin and Eastern
  Uinta Mountains.

* Through Tuesday evening

* Scattered to numerous thunderstorms with heavy rain are expected
  over the watch area. With a moist airmass in place, the threat
  for heavy rainfall will continue into the overnight hours.
  Another round of afternoon thunderstorms is expected on Tuesday
  afternoon lasting through midnight Tuesday night.

* Flash flooding due to heavy rainfall is possible, especially
  over already saturated soils and areas of steep terrain. Steep
  canyons, burn scars, and normally dry streams, washes and
  arroyos are most susceptible to flash flooding. Water can rise
  quickly downstream of heavy rain, even when a thunderstorm is
  miles away. Rock and mud slides, and high water flowing across
  roads, are also possible which could impact travel.


A Flash Flood Watch means that conditions may develop that lead
to flash flooding. Flash flooding is a very dangerous situation.

You should monitor later forecasts and be prepared to take action
should Flash Flood Warnings be issued.
